refs #5801 merge 5801 (improve threaded stress test framework) to main: now the loader is used for sufficiently large tables, correctness tests fill tables with zeroes while performance tests fill them with bytes based on compressibility, and both use similar code paths for key/val generation for better consistency and readability

// The Way Things Work:
//
// Threaded stress tests have the following properties:
// - One or more DBs
// - One or more threads performing some number of operations per txn.
// - Correctness tests use signed 4 byte keys and signed 4 byte values. They expect
// a table with all zeroes before running.
// - Performance tests should use 8 byte keys and 8+ byte values, where the values
// are some mixture of random uncompressible garbage and zeroes, depending how
// compressible we want the data. These tests want the table to be populated
// with keys in the range [0, table_size - 1] unless disperse_keys is true,
// then the keys are scrambled up in the integer key space.
